To'aZZ ill-710m it may concern:

,Be it known that I. ANGELO Pnnnr, a citizen of the United States, residing at Vaten town, in thecounty of Middlesex and State of Massachusetts, have invented a new and use t'ullViping Mechanism, of which the following is a specification, reference being bad therein to the accompanying drawing.

This invention is anovel wipingmechanism. The present case is a companion to my copending' case entitled shoe lasting machine. filed August 14. 1919, Serial No. 817;

1.98, which latter discloses a complete ma chine embodying pulling-over mechanism, toe and heel wiping mechanisms, and shoe holding;- jack shiftableto change the shoe position between pulling-over and-wiping. The present case has reference more particularly to the heel wiping mechanism, which is only generally illustrated insaid copending case. It is to be understood, however, that, while the present mechanism is designed and adapted more particularly to the wiping of heel ends of shoes, many features might be used in toe wiping mechanisms; and the mechanism herein shown would be useful. not merely in a complete pulling-- over and wiping machine, as in saidcopending case, but also in other orms of lasting machine, for example,-the well known bed laster. in which wiping, but not pullingover ispe formed; and the scope and utility of the present invention are not intended to be restricted in these respects- The main object of the-present invention is to att'ord a shoe wiping mechanism operating in a more efficient andconvenient man.- H

, ner and with better results in the product,'as

compared, for example, withthe mechanism generally shown in my prior Patent No;

1.5260934, patented March 19. 1918. Another olriect is to afford an improved construction .forsymmetrically shifting the,

of shoes, and. adapted for examplepfor use in a lasting machine suchas is illustrated'in said copending case, wherein the, right side of Fig. 1 willbe seen the same mecha-.

nism as Fig. 1 hereof, thesame beingishowu in appropriate surroundings and withf' propr'iate fittings and adjustments unnecessary to repeat in. the present case. 7 Indeed,

for convenience in the present case the" wiping mechanism has been changed from the inclined position indicated in the cop'end ing case,,and whichv it would possess in practice, to a horizontal position to afford more.

wiperplates 17 above it. ,Without' at first going into" details ,of the immediate fittin s Fig; 4 is a top plan View of certain parts Thecentral section, Figure '2, also shows the clamping-pad 16 and the and actuation of these parts, I will on y here call attention to the operating or wiping handle 18, at the right side of Figure 1, through which the advancing and wiping motions of the plates and their carrying means are effected. These parts are all carried substantially at the top of a series of shiftable or adjustable supporting members which may be termed carriages and which itwill be convenient to first enumerate from the top downward, giving their motions, afterwards commencing at the bottom and giving details and structure and fittings of each.

The heel pads and the wiper plates and their immediate carrying parts are sup ported by a circular carriage 20. This is capable of adjustable rotation for the purpose of altering the lateral tilt or slant of the wiper plates to accord with the position that the shoe may occupy in the holding jack, the shoe seldom or never being horizontal at the heel end.

This laterally tiltable carriage 20, which is seen to be generally cylindrical, is mounted within the second carriage 21, this being adapted to be adjusted bodily, upwardly and downwardly, to bring the wiping mechanism to the correct height.

The rising and falling carriage 21 is in turn mounted on the next carriage 22 which has advancing and receding movements, that is, it shifts or slides longitudinally toward and from the shoe and serves the purpose of bringing the wiping mechanism up into engagement with the heel of the shoe.

This sliding carriage 22 in turn is mounted on'the carriage 28 beneath it, the same being tiltable longitudinally so as to enable the wiping plates to be adjusted in this respect to accord with the shoe.

The longitudinally tilting carriage 23 is fulcrumed upon a circular or dislrlike carriage 24, which is centrally fulcrumed and capable of rotary shifting movements upon the next lower or swinging carriage 25. The rotary carriage enables the direction of wiping action to be reversed for reversal of the machine for right. and left shoes alternately. The swinging carriage 25 carries all of the preceding carriages and the wiping mechanism bodily across the axis of the machine from front to rear, and vice versa in the act of=reversing the mechanism for right andleft shoes. 1

This swinging carriage 25, with all of the carriages above it, is swingingly supported upon the right hand end of a transversely slidingcarriage 26 capable of a substantial bodily movement across the machine from front to rear, and reverse, in the changing over of the machine from right to left shoes and vice versa.

The transversely sliding carriage 26 is dovetailed directly at the top of an upright carriage in the form of a swinging post 27,

which by proper adjustment is thus capable of carrying with it toward or from the shoe and jack the entire wiping mechanism with all the intermediate carriages.

The swinging post 27 is fulcrumed at 28 to a base portion 29 of the machine, as more fully shown in the aforesaid copending case. Near its upper part the post is provided with a threaded sleeve or nut 30, centrally pivoted at 31, and engaged by a threaded rod 32 having handle 33 at its right extremity and connected by a universal joint 34 to a fixed part 35 of the machine. By simply turning the handle 33 the whole wiping mechanism is caused to adjust as desired, toward or from the jack and shoe.

The transversely sliding. carriage 26 is dovetailed upon the top of the swinging post 27. The carriage 26 has a rightward extension 36, and other parts having to do with the fittings of the next carriage. Secured to the top of the post 27 is a front stop 38 and a rear stop 39 adjustable for determining the extreme transverse positions of the carriage 26. The carriage 26 may be thrown across the machine by hand power, as will be described.

The transversely swinging carriage or table 25 is pear shaped and is fulcrumed at 41 on the extension 86 of the-carriage 26. It is a fiat, platelike member resting flatly on top of the carriage 26, and its free or left end is adapted to swing forward and rearward. To determine its extreme position. the following stop mechanism maybe employed. Through a curved slot in the carriage 26 extends a boss 42, its under side recessed at 43, and into this recess extends upwardly one or the other of a pair of adjustable stops 44. The plan of these is indicated in dotted lines in Figure 3, and the structure of one of them is shown in Figure 2. Each stop 44 is mounted on a carrier 45. A pair of transverse rods 46 and 47 extend through holes in the two carriages. The stops or pins 44 are springepressed up wardly to the positionshown in Figure 2, and when. in this position the swinging car riage 25 is locked against transverse shifting. In order to unlock the same to permit the shifting of the carriages, the stop pins 44 may be pulled down by reason of the tooth and rack engagement 48 between the lefthend rod 46 and the stop pin. At the front end of the rod is a handle 49. This has merely to be lifted to lower the stop pins and thereby free the swinging carriage for its reversing movements. 'lhere are symmetrically opposite stop pins. as statedpand these may be symmetrically adjusted toward and from each other by the transverse rod 47, which has right and left threads, as seen in Figure 3, so that when the handle 50 at the front end thereof is turned, the stop pins may be set where desired and thus predetermine the amount of swing or throw of the carriage across the axis of the ma chine. In Fig. 2 the carriage 25 is supposed to have been swung enough. for pin 44' to engage slot 43. i

The rotary turret or carriage 24 is mounted'flatl-y upon the swinging carriage 25. Its rotation is for the purpose of setting the axis of the wiping-devices to the axisofcthe shoe when the wiping devices need and general plan of swinging and rotating the wiping mechanism to reverse the machine is indicated in Figs. 27 and 28 of said Patent 1,260,034.

It should be explained that, for con venience of illustration, the carriages 25 and 24 are shown in Fig. 3 in acentral or neuthrown alternately to the far or rear side and the near or front side for right and left shoes. In order to effect the automatic rotation of the carriage 24 when shifted transversely with the carriage 25, the following may be provided. At the right edge of the rotary carriage is provided a curved toothed rack 54. This is engaged by a second rack provided at the left edge of a rotary toothed member 56 mounted directly on the carriage 25. The right edge of member having a rack 57 of smaller radius is engaged by toothed member or pinion 58 which is also mounted, upon the underlying carriage 26. TV hen the carriage 25 is swung tothe rear or front, the member 56 runs around the pinion 58, which rotates the member, which in turn rotates the rotary carriage 24. Thereby, as the carriage 25 is swung'across the machine, the carriage 24 is rotated in the reverse direction so that the axis of the wipers is maintained in the proper relation to the shoe. Toincrease the swing of the wiping mechanism the pinion 58 may be rotated while it is functioning with the other members 56 and 54. To this An advantageous feature hereof is the abilityto effect all of the reversing motions" for ri ht orleft shoes b -a sin le ,motion' I b y c i or a lever orcontrolpart. Thus, in Figure 3 is seen at the farside of the carriage 25 a boss 61ff'rom which extends a link 62" rearwardly'to an upright reversing lever 63, seen in Fig. 1. Vlhen this lever 1s thrown rearwardly, it first causes" thecarriage 26 to. sliderearwardly-until it contacts n sa 39. The continued motion swings the'car I riage. 25 rearwardly until it is broughtto rest by the engagement: of oneofthe,

steps I 144 in the recess 43.- During fthis i 0 swinging motion the pinion 55 causes "the rotation of the carriage 24, wh ch thus also reverses itself. On pulling forwardly the reversing lever 63,.the three motions are" I reverse' ,-namely, the forward sl ding of g carriage '26, followed by the swinging of carriage25, and the rotation of carriage 24; although the sliding-might occur last.

At tlie top side of the carriage 24 are a pair of spaced apart ears InF-ig, tllGSBGfil'Sdl-l seen but allv parts above them In Figure 2,..thecarr1age 23 are omitted. is shown as trunnioned on the ears 65 as fulcra, so as to permit a rocking 01 51011- gitudinal tilting 1n the carriagev 23 forgthe purpose of adjusting the wiper. platesin that respect. The following devices are shown in effecting this adjustment. of the ears 65 upstandingfrom carriage 24 has a rightward extension 66 within which One is engaged a rotatable rodorscrew 67.

This, as shown in Figure 1, passes through a threaded block 68 swiveled' upon the cari riage 23, and thence upwardly to where at its upper end it has within convenient access a handle 69. By turning the handle the screw is rotated, and the block andrear end of the tilting carriage'zare lifted or dropped, as desired.

The top of the tilting carriage 23 forms a sli deway in which longitudinally slides the carriage 22. .Th s carriage is adapted entire wiping head from; retracted position up to the shoe. It has 'to be brought forcibly into place so that; the heel clamps will engage snugly in position about the shoe heels For effecting this movement,

to have a large movement to. bring the A long leveror handle 73mayy be manipulatedQbeing thrown to'the left to ad'vance'the wiping mechanism to the,

shoe. When in position the carriagemay' be locked as follows, to' leave theoperators hands free for the wiping operations. On top of thecarriage 23 is a toothed rack or ratchet 75, and this is en aged by a pawl 76 on the carriage 22 so t at the pawlengages the ratchet and locks the carriage in most advanced. position. A spring 77 tends to hold the pawl against the ratchet, and a handle 78 is used for unlocking when it is desired to retract the Wiping mechanism after the shoe is completed.

The carriage 22 is formed with upwardly extending guides 80 and overlying confining platesSl within which is mounted and slides vertically the carriage 21. The last mentioned carriage has flat bearing surfaces at the sides to co-operate with the verticalguides, and is shown in Figure 6 as provided with a hollow or shell-like casing or cylinder 82 for containing and tiltingly supporting the parts shown within the same. The up and down adjustment of the carriage 21 is effected by handle 84 provided at the top of a rotatable rod 85 which, at its lower end, is provided with a gear 86, which gear in turn engages gear 87 mounted at the foot of a threaded rod or screw 88 engaging a threaded boss 89 at the under side of the rising-and falling carriage 21. By turning the handle 84: the wiping devices are thus adjustably raised or lowered as desired.

The carriage 90, which as a whole is cylindrical, may be rocked within the cylindrical portion 82 of the carriage 21 by means of the upstanding handle 90, secured to the forward part of the carriage. As best seen in Figs. 6 and 8, the carriage 9,0 is built up, having a top or cover section 91, a middle section 92 and a bottom section 93, shaped to give proper bearing surfaces for the tilting motion, and rigidly interconnected into a unitary member or carria 'e.

The coversection 91 extends leftward beyond the enclosing cylinder 82, as shown in Fig. 2, and the middle and bottom sections are similarly extended and shaped. for the purposes and functions which are to be described. Generally speaking, the middle section 92 affords support for the wiper plate carrier and fittings, shown in Fig. El, while the bottom section 93 or the carriage 20 forms the support for the heel engaging or clamping devices illustrated separately in Fig. 5. 7

Referring first to the heel clamping mechanism, the sect-ion or support 93, which is shown in plan view in Fig. 5, has rigidly secured to its left end an extension or head 94:, which supports the clamping mechanism. Longitudinally slidable in the support 93 is a bar or carrier 95, which at its left extremity carriers part oi? the heel clamping devices. This carrier bar is centrally slotted at 96, and provided in said slot with a spring 97, tending to press the bar leftward. A pin 98 extendsupwardly from the support 93 into the right end of the slot 96, as shown also in Fig. 2, this tormthe leftward movement ing stop limitin a d also aiiording an abutoi? the carrier 95, ment for the action i the spring 96.

The heel clamping devices comprise, first, the pad 10, which may be oi leather. or other flexible material, and is backed up and acted upon by a series of clamping blocks, 100 at the heel apex, and 101 at the sides. The apex clamp block .100 is mounted at the left end 01 the carrier by a pivot allowing play, so that the block may adjust itself in its clamping action. j fit each side oi the clamp pad 16 are three clamp blocks 101. .ach pivotally mounted on a clamp blocl; carrier 102, which itself, is universally pivoted upon a carrierlei 'er 103, tulcrumed at 10sto the head 9%, and having an extension lior cooperating with a cam mounted on the carrier This mechanism duplicated at the two sides, and the cam 100 is double or wedge-like, so as to throw outwardly both lever arms 105, and thereby throwinwardly the side clamping blocks against the heel. Symmetrical adjustment of the side clamping parts may be effected, namely, by the right and left screw device 107, shown in Fig. 52, acting to adjustably shift the fulcra 10 toward and from each other.

The action of the heel clamping devices may be as follows. The operator bythe handle '73 bodily thrusts the carriages 22, 21 and 20 toward the heel of the shoe.

Euring this action the heel ape clamp block 100 is first brought to a stop by the forcible resistance of the shoe to its further advance. Thereupon the carrier or slide '95 becomes relatively stationary, whereas the support or section 93 with its head. 9 1 continues to be pressed to the left, against the resistance of the spring 90. The cam arms 100 are thrust apart by the wedge cam 100, and thereby the side clamp blocks 101 are brought torcihly toward the shoe at the sides of the heel. When the parts are firmly and snugly in place, the operator may release the handle 73, inasmuch as the locking pawl and ratchet 75, 76 is arranged to hold the parts in their advanced position until after the Wiping, when the same are intentionally released by the handle 78. In the meanwhile it will be understood thatthe Wiper plates and mountings, on the middle section or support 92 ot the carriage 20, have remained idle, except for the bodily advance of the car riage toward the shoe.

The section or support 92 for the wiper plates and fittings is provided at its left end, as best shown in Fig. 4L, with an enlarged extension or head 108. This, like the head 9% of the bottom. section 93, is a flat, plate-like structure, but preferably differs in having an upstanding edge flange or rim 109, within which lie the wipe plates 17, 1'7.

The section or support 99 forms a slideway 180 Containing a longitudinally sliding bar'or wiper slide 110, which is the part that is advanced and retracted: during the actual wiping movements. 1 will, therefore, first describe the connections-for advancing and retracting this slide to operate the wiper plates. 7

As seen on Figs. 1 and 2, the; upper part of the carriage 21 is provided with a rear wardly extending bracket 111, and pivoted to this bracket is a link 112 extending to the right. The wiping handle 18, which has already been mentioned, has its rear extremity pivoted to the link 112 and 113. At an intermediate point the lever or handle is-provided with a swivel connection 114 to the rear or righthandextremity of the wiper slide 110. By now swinging the forward end of the handle to left and right, the wiper slide is advanced toward the shoeand retracted.

The reciprocating wiper slide 110 arranged to effect both the advancing movements of the wiper plates toward the heel, and their iii-swinging movements toward each other. In orderto enable this to be effected, the plates 17 are themselves mounted, not onthewiper slide 110, but on a wiper carrier 116, which-is shown in the form of a bar slidingly mounted within the wiper slide. The wiper carrier at its left end, as shown in Fig. 4, is provided with a pair of curved guides 117, engaging in slots 118, formed in the plates 17. These curved guides and slots are struck about the apex of the wiping contour as a center, so that the plates will swing about their'own meeting point and thus preserve continuity of wiping edge, a feature already shown and cov ered in a prior patent. of mine.

In order toeffect the swinging movements of the plates toward each other, a pair of links 121 is shown, extending respectively from the two plates rightward to the ends of across piece 122, formed on or rigidly secured to the wiper slide 110. V

. The general plan of action is somewhat similar to that of the clamp blocks already .123, which causes the wiper carrier 116 to come to rest with the wiperplates in accurate w ping position. This means that the apex of the wiping contour is brought slightly over the shoe, so as to wipe the upper at that place, while the continuing movement of the handle swings the plates in such position that the plate Spring 128 will at the sides, so asto completezandpenfectthe wiping action. I believe it to be new herein to so control the wiper plates that'v-theiswingr, ing in or side wiping can-not be. effected until the plates have advancedfover the heel apex to'the most advantageousposition. 1 1 1n:

While the stop 123 mightbe provided different places and forms, it is shown as an adjustable screw stop mounted at the extreme forward portion ofthe, wiper carrier 116 in such position as to abut against the; heel clamp, block 100, as. best seen in Fig.2. To preserve and restore the normal rel-i1: 2

tion between the wiper slide and the wiper carrier, yet to permit the relative motion referred to, a yieldingeleme'nt or spring'125 is shown, mounted in a longitudinal recess in the carrier 116, its rear end contacting to thrustthe post 126 and wiper slide. back to the normal 1 relative position shown in Figs. 2 and4, but'for the following device which serves to ;retain them slightly vads vanced, so as to leave the wiper plates slightly over the margins of the shoe at the sides at the completion of the'wiping. This has certain advantages, including the tem'- porary holding of the wiped'edges in place, during the operation Qftacking or otherwise securing the edges. Alsothe bodilyreti'ac- 1 tion of the wiper devices tends to give a 1on gitudinal smoothing action on the wiped ma terial, somewhat improving the. final result. To theseends a latch or trigger 127 is. provided, pivoted upon the wiper carrier 116 in act to thrust the latch behind, that is, to the right side, of the post 126, when thelatter has been advanced leftward during the wiping. This latch, therefore, acts to block the complete return of the post. In'other words, the wiper slide and wiper carrier are prevented from taking their relativeposition shown," but the slide is held slightlyrelatively advanced, so as; to hold the wiper plates over the edge'of the material, as stated.- This condition of the parts will be maintained until the wiper handle 18 is thrown completely to the right, when the tail 129 of the latch is struck by a pin or roller .130, standing downwardly from a slide 131, adjustably 1 mounted by a screw 132 on the top; portion or section 91 of the carriage 20 as seen in Fig. 7.

The wiping operation may take place somewhat as follows. When the hand1e73 is thrownto bring the heel clamping nstillanism to the shoe, this brings thewiping mechanism approximately to position. Up

on the actuation of the wiper handle 18, the

wiper slide 110 is thrown to the left. It can ries with it the wiper carrier 116 and the wiper plates. The stop pin 123, however, soon meets the block 100, stopping the advance of the wiper carrier and plates. The continued actuation of the wiper plates and handle 18 continues the advancing of the slide 118, and thereby throws the wiper plates toward each other, they having alreacy been brought accurately to proper wiping position, slightly overlying the heel apexof the shoe. The spring now tends to return the wiper slide to the right, and the operator allows this by letting up the pres sure on the handle. hen the post 12% contacts the latch 127, the handle may be released and the parts will remain in that position. The wiped margins will now be held by their extreme edges and the tacking or securing of the leather may be performed at leisure. When completed the handle 18 is thrust completely to the right, retracting the wiper slide and wiper carrier and tripping the latch to allow the wiper plates to separate to their normal position, and the parts are in readiness for a new operation.

It will thus be seen that l have described a wiping mechanism embodying the principles and attaining the a vantages of the present invention. Since many features of design, arrangement, combination and detail. may be variously modified without departing from the novel principles involved, no limitation to such features is intended except in so far as specified in the appended claims.
